VISIBLE DISPLAY ATTACHMENT FOR MEASURING PUMPS.

' Application filed November 14, 1923. Serial No. 674,769.

To all whom it may concern:

Be it known that we, WILLIAM S. TOWN- SEND and FRANKE. DoUeLAss,citizens of the United States, residing at Rochester, in the county ofBeaver and State of Pennsylvania, have invented certain new and usefulImprovements in Visible Display Attachments for Measuring Pumps, ofwhich the following is a specification.

Our invention relates to the visible twotube display attachment formeasuring pumps shown in Fig. 4 of our Patent No. 1,455,235, May 15,1923.

The object of the invention is to provide a display attachmentparticularly adapted for oil measuring and dispensing pumps; saidattachment comprising, as in Fig.4 of the patent referred to, a displaycontainer formed of parallel glass tubes connected at their upper endsfor through passage of the oil or other liquid and provided at theirlower open ends with a base having an inlet for connection with thedischarge side of a pump opening into the lower end of one of said tubesand an outlet port communicating with the lower end of the other of saidtubes, whereby the container will be constantly filled with liquid fromthe pump while being dispensed so that the purchaser may see thecharacter of the liquid being supplied him.

A further object is to provide a contracted or valved discharge nozzlefor said outlet port and a normally closed air vent at the upper end ofthe container to permit of readily filling the container and thereafterholding the contents of the container therein while the pump is not inoperation.

These objects we accomplish by the construction shown in theaccompanying drawing, in which:

Fig. 1 is a central vertical section through the display attachment.

Fig. 2 is a similar view at right angles to Fig. 1.

Fig. 3 is a section on line 33 of Fig. 2 looking down.

The top or cap 1 of the display device is shown as hollow so that itschamber 2 will form a through connection for the upper open ends of twovertical parallel glass tubes 3 and 4, said. upper ends being seated inseats 5 and 6 formed in the lower side of the top or cap 1 and restingon suitable gaskets 7. The ea or top 1 is further provided with anormally closed vent valve 8 and the central portion of the cap isprovided with a bolt aperture 9.

The lower open ends of the tubes or cylinders 3 and 4 are seated ongaskets 8 within seats 10 formed in the uppers'ideof the base 12. Thebase 12 is formed with an inlet port 13 leading into the lower open endof the glass tube 4 and adapted for connection with the discharge sideof a pump, while the opposite side of the base has a discharge port 14leading down from the lower open end of the tube 3 to a discharge nozzle15 screwed'into the lower end of said port 14. This nozzle has arestricted outlet provided with a valve seat 16 at its lower end and anupwardly closing valve 17 closing against said seat. The stem 18 of thevalve is guided by two crossbars 19 within the nozzle and is movedupwardly by a spring 20 which rests between the upper crossbar 19 andthe nut or head 21 on the upper end of the valve stem.

A tie rod 25 is screwed at its lower end into a threaded opening 26 andpasses up through the aperture 9 in the cap or top 1, where it isprovided with nuts 27, 28 which, when tightened, will draw the cap 1 andbase 12 towards each other and so press the tubes 3 and 4 tightly totheir gasketed seats.

The attachment is intended to be used in lieu of the single displaycylinder shown in our Patent No. 1,450,994 and operates as follows: uponopening the vent 8' and starting the pump the oil or liquid will beforced up through'tube or cylinder 4 and then pass down cylinder 3 intothe discharge nozzle 15; the restriction of the nozzle area or outlet bythe valve 17 causing the tubes to be first filled, after which the vent8 will be closed and the oilor liquid will remain in the display tubes 3and 4: for display purposes until the pump is operated for dispensing.Then the force of the liquid leaving the pump will move the body ofliquid beingdisplayed in the two tubes and cause it to open the valve 17in the discharge nozzle and issue forth for dispensing purposes. Theclosing of the air valve 8 and the cessation of the pumping causetheliquid to remain in the tubes for display purposes until dispensingof the liquid is again required. In order that the dealers name or othermatter may be exhibited, the adjacent faces of cap 1 and base 12 areprovided with pins or lugs 30, 30 which project towards each other, asin Fig. 2, at opposite sides of the tie rod 25 and between the glasstubes or cylinders 3 and 4. Tags bearing the dealers name or othermatter and formed of oblong plates 31, 31 are placed with their endsbehind these lugs 30, 30, their backs against the tie rod 25 and theirlong sides against the glass cylinders, thus concealing the tie rod fromboth sides of the attachment.

While we havvevshown our display device adapted to be used in lieu ofthat shown in our Patent 1,450,994, it is obvious that it may by slightchanges in the base be used as in Fig. l of our Patent No. 1,455,235,the inlet from the pump being then placed in the bottom of the base andthe outlet or discharge nozzle at the side.

It is obvious that when the display is only desired during thedispensing, the valves may be omitted so that an uninterrupted flow willbe made from the pump up through one tube and down through the other tothe outlet. a

What we claim is: a

1. A visible display container for pumps, comprising a pair of paralleltransparent tubes connected at their upper ends for through passage ofthe liquid, and a base for the lower open ends of the tubes;'said basehaving a pump supply inlet port opening into the lower end of one of thetubes and an outlet or discharge communicating withthe lower end of theother of said tubes,

whereby the liquid will be forced by the pump up through one tube anddown the other one to the outlet to exhibit same.

2. A visible display container for pumps, comprising a pair of paralleltransparent tubes connected at their upper ends for through passage ofthe liquid, a base for the lower open ends of the tubes; said basehaving a pump supply inlet port opening into the lower end of one ofsaid tubes and an outlet or discharge communicating with the lower endof the other of said tubes, and a discharge spout or nozzle leading fromsaid outlet or discharge port and having a re stricted area acting tohold the liquid in the two tubes for exhibition purposes.

3. A visible display container for pumps, comprising a pair of paralleltransparent tubes connected at their upper ends for through passage ofthe'liquid, a base for the lower open ends of the tubes; said basehaving an inlet port opening into the lower end of one tube and anoutletor discharge port leading from the open lower end of the other of saidtubes, and a discharge spout leading from said out-let port and having avalve which when closed will hold the two tubes filled for exhibitionpurposes.

4:. A visible display container for pumps, comprising a cap or tophaving a through passage and a normally closed air vent, two open-endedtransparent tubes connected at their upper ends by said passage, a baseon which the lower ends of the tubes are seated, means for connectingthe cap and base; said base provided with an inlet port leading from thelower end of one tube and adapted for connection with the discharge sideof a pump and a discharge port leading from the lower end of the othertube, and a discharge nozzle for the outlet port provided with anoutwardly opening spring-pressed valve.

5. A visible display container for pumps, comprising a cap or top havinga through passage, a pair of transparent tubes communicating at theiropen upper ends with said passage, a base having a pump-connect inginlet port leading to the lower open end of one tube and an outlet portleading from the lower open end of the other tube down to the middleportion of the base, a discharge nozzle depending from the saiddischarge port and provided with an outwardly opening discharge valve.

6. A visible display container, comprising a cap having a throughpassage, parallel display tubes connected at their upper ends by saidpassage, a base having inlet and outlet ports with which the respectivelower open ends of the tubes are connected, a central tie rod connectingthe base and cap, tag-retaining devices on the adjacent faces of thecapand base at opposite sides of the tie rod; whereby a tag or tags maybe held in place bet-ween the tubes.

7. A visible display container, comprising a cap having a throughpassage, parallel display tubes connected at their upper ends by saidpassage, a base having inlet and outlet ports with which the respectivelower open ends of the tubes are connected a central tie rod connectingthe base and cap, tag-retaining devices on the adjacent faces of the capand base at opposite sides 01 the tie rod, and an oblong tag held bysaid retaining devices with its back to the retaining rod and its sidesedges adjacent to the two tubes.

In testimony whereof we a'liix our signatures.
